In this study，We choose Dian dian hong as materials to study the biological effect of low energy Ar+ Ions implantation。The relationships between the materials of the budding rate and the survival rate and the irradiated dosages of low energy Ar+ Ions implantation are explored. Further more, we measure the activity of peroxidase isozyme and the kind of peroxidase isozymes and esterase isozyme in leaves of dian dian hong after implantation by low energy Ar+ Ions. The results improve that different mutation dosages of Ar+ Ions implantation can all make dissociation in the materials of budding rate and the survival rate and their growth and development in each step. Between the dosage of 1×1017Ar+/cm2 and 3×1017Ar+/cm2 the budding rate curve of Dian Dian Hong could take a “saddle pattern” with the increased Ar+ Ions implanting dosage. The survival rate takes the similar change regulation with the budding rate, but has lower amplitude. With Ar+ Ions impanted in low dose, the activity of peroxidase isozymes increase along the Ar+ Ions implanting dosage, but when Ar+ Ions are implanted in higher dose, the peroxidase activity decrease. The band of isozymes suggest that POD increase one band in the dosage of 2.5×1017Ar+/cm2 and 3×1017Ar+/cm2, but these lose in the dosage of 1.5×1017Ar+/cm2 and 3×1017Ar+/cm2 ; the amount of Est bands increase in the dosage of 1.5×1017Ar+/cm2 and 3×1017Ar+/cm2.
